South Korean President Moon Jae-in on Thursday proposed an unconditional dialogue with the Democratic People's Republic of Korea (DPRK) if Pyongyang stops any nuclear and missile provocations.

Moon made the remarks at the 17th anniversary event to celebrate the June 15th North-South Joint Declaration, which was made when late South Korean President Kim Dae-jung and late DPRK leader Kim Jong Il held the first inter-Korean summit meeting in Pyongyang.

The DPRK's determination to give up its nuclear program would become an evidence of its will to implement the inter-Korean agreement, and if Pyongyang makes the determination, South Korea will actively help, Moon said.

The South Korean leader said his government will be able to comprehensively discuss various issues, ranging from the DPRK's complete denuclearization, the building of peace regime on the Korean Peninsula and the normalized diplomatic relations between the DPRK and the United States.

It marked the first time that Moon mentioned the three issues, though he set a precondition of no provocations, since he took office on May 10.

Moon said that though the DPRK urged the implementation of the June 15th declaration and the Oct. 4th North-South Declaration, Pyongyang advanced its nuclear and missile capability and broke what it urged.

The Oct. 4th declaration was made at the second inter-Korean summit meeting, which was held in Pyongyang in 2007 between late South Korean leader Roh Moo-hyun and late DPRK leader Kim Jong Il.

Though South Korea will make its own efforts, the DPRK should do its own, Moon noted.

Referring to the July 4th Joint Statement in 1972 and the 1991 Basic Agreement as well as the two declarations, Moon said a series of the previous inter-Korean agreements would become a grand principle in improving inter-Korean relations under his government.

The president urged Pyongyang to give up its nuclear development, adding that the DPRK's nuclear and missile developments posted a serious threat to peace and stability in the region and the world.
